Anti - brush test method and indictor are put forward through test 通过试验提出了半刚性基层材料抗冲刷试验方法和评价指标。
Lean concrete is a good type of base material , which can meet the demand of large and heavy traffic 贫混凝土是一种优良的基层材料,可满足大交通量和重载路面的使用要求。
The paper also concludes that the fatigue property of lean concrete is better than the semi - rigid base materials 通过对比,得出贫混凝土的疲劳性能优于其他常用半刚性基层材料。
A series of tests on semi - rigid materials and bituminous mixtures are carried out to proposed the value range of material parameters 结合当地料源对常用的半刚性基层材料及沥青混合料的性能进行了大量的试验研究,并给出适合本地区的材料参数取值范围。
First , the fatigue feature of lean concrete is studied by fatigue test in this paper . it is proved that lean concrete has better fatigue feature than semi - rigid materials 本文通过疲劳试验对贫混凝土的抗疲劳特性进行了研究,表明贫混凝土具有比常用的半刚性基层材料更加优良的疲劳性能。
